This award supports a one year project with Dr. J. Christensen of Bigelow Laboratory for Ocean Sciences that will attempt to make respiration rate measurements of selected benthic infauna. The measurement of benthic respiration rates is critical to our understanding of the consumption of organic carbon in shelf and near shore waters. However, biological rates are some of the most difficult environmental measurements to make, and the investigators will apply a sensitive biochemical assay for respiration, the measurement of electron transport system (ETS) activity. The ETS measurements will be calibrated with laboratory oxygen consumption measurements and respiration under a range of environmental conditions will be investigated. The field study will be done in the near shore waters of southern Maine.

该奖项支持与毕格罗海洋科学实验室的J·克里斯滕森博士合作的一个为期一年的项目，该项目将试图对选定的底栖动物进行呼吸速率测量。底栖生物呼吸速率的测量对于我们理解陆架和近岸水域有机碳的消耗至关重要。然而，生物速率是最难进行的环境测量之一，研究人员将应用一种敏感的呼吸生化分析方法，即电子传输系统(ETS)活性的测量。ETS测量将与实验室耗氧量测量进行校准，并将调查一系列环境条件下的呼吸。实地研究将在缅因州南部的近岸水域进行。
